Abstract

A method in a user equipment for predicting an available throughput for uplink data to be sent from the user equipment to a base station over a radio link. The user equipment obtains ( 201 ) an information about a past scheduling of the user equipment. The user equipment obtains ( 202 ) a radio quality measure related to the radio link. The user equipment predicts ( 204 ) the available throughput based on a relationship between the information about a past scheduling of the user equipment and one or more previously obtained pieces of information about the past scheduling of the user equipment. The user equipment predicts the available throughput further based on a relationship between the radio quality measure and of one or more previously obtained radio quality measures. The user equipment predicts the available throughput further based on a previously obtained throughput. The previously obtained throughput is associated with the one or more previously obtained pieces of information about a past scheduling and the one or more previously obtained radio quality measures.

obtaining first information about a past uplink scheduling of the user equipment;
determining an estimated cell load of a cell served by the base station, based on the first information about the past uplink scheduling of the user equipment;
determining an estimated throughput for uplink data to be sent from the user equipment to the base station over the radio link, based on a relationship between the estimated cell load and a previously obtained cell load; and
optimizing a quality of service based on the estimated throughput;

wherein the method further comprises:
obtaining a first radio quality measure related to the radio link; and
determining the estimated throughput, further based on:
a relationship between the first information about the past uplink scheduling and previously obtained information about the past uplink scheduling;
a relationship between the first radio quality measure and a previously obtained radio quality measure; and

a previously obtained throughput for the uplink data, the previously obtained throughput being associated with the previously obtained information about the past uplink scheduling and the previously obtained radio quality measure.

2. The method according to claim 1 , wherein obtaining the first information about the past uplink scheduling further comprises:
for a past uplink scheduling performed at a Transmission Time Interval (TTI), obtaining at least one of:
the number of physical resource blocks that are scheduled for the user equipment for a priority class;
the total number of physical resource blocks in a cell where the user equipment is located; and
information about a buffer status of the user equipment, the information about the buffer status indicating at least an amount of uplink data per priority class.

3. The method according to claim 1 , wherein the cell load is at least one of a current or a future cell load of the cell.

4. The method according to claim 1 , further comprising:
displaying the estimated throughput on a screen of the user equipment;
receiving a user input in response to the displayed estimated throughput; and
optimizing the quality of service further based on the user input.

5. The method according to claim 1 , further comprising:
displaying the estimated cell load on a screen of the user equipment;
receiving a user input in response to the displayed estimated cell load; and

7. The method according to claim 1 , wherein:
the previously obtained cell load is associated with the previously obtained information about the past uplink scheduling; and
the method further comprises:
determining the estimated cell load further based on the relationship between the first information about the past uplink scheduling and the previously obtained information about the past uplink scheduling.

8. The method according to claim 1 , further comprising:
determining an actual throughput for uplink data to be sent from the user equipment to the base station over the radio link;
determining an actual cell load of a cell where the user equipment is located, the actual cell load being associated with the actual throughput; and
storing, in a storage device:
